[0015] When the round block contacts the touch button, the external alarm device sounds an alarm, eliminating the need for human eyes to observe the water level.

[0016] Preferably, a weight ball is fixed to the bottom of the floating block, and a groove matched with the weight ball is provided on the top of the humidifier chassis.

[0017] The weight of one end of the float is increased by a counterweight ball, so that the float can pull the round block to move when it falls.

[0018] The beneficial effects of the utility model are:

[0019] When the water level is sufficient, the float floats in the water and abuts against the bottom end of the fixed tube. At this time, the round block is away from the touch button. When the water level drops, the counterweight ball pulls the float to move downward with the water level, and the float pulls the round block upward through the rope. When the water level drops to the warning line, the round block contacts and presses the touch button, causing the external alarm device to sound an alarm, thereby reminding people to add water to the humidifier. This effectively solves the problem of low practicality in the prior art that most humidifiers are observed by human eyes during use, and cannot remind staff. BRIEF DESCRIPTION OF THE DRAWINGS
